1 Claim.

This invention relates in general to information storing mechanisms and in particular to a card holder adapted to position a plurality of switches in accordance with openings formed through the card.

It is oftentimes desirable to store information which may be used to actuate a plurality of switches.

For example, the co-pending patent application of Horst M. Schweighofer and Gordon E. Nicholson, entitled Shaft Positioning System, Serial Number 143,498, filed February 10, 1950, discloses a card control system which may be selectively turned to any one of a number of positions so as to position a shaft to a desired position.

It is an object of this invention to provide a card holder for use with such a system and which actuates a large number of switches.

Further objects, features and advantages of this invention will become apparent from the following description and claims whenread in view of the drawings, in which:

Figure 1 is a top view of the card holder of this invention;

Figure 2 is a side view of the card holder of this invention;

Figure 3 is an enlarged detailed view of a pair of switches and card in the actuated position;

Figure 4 is a detailed view of the releasing mechanism of the invention; and

Figure 5 illustrates a card which may be used with this invention.

Figure 1 illustrates a base plate I which is connected by stand-offs H to a second plate l2. A plate I3 is slidably received on the stand-offs H and is formed with a card receiving slot H. A number of channels l are formed in plate l3.

A plurality of switches I5 are mounted to a spacer member I! which is mounted to the plate It]. The switches I6 might be micro-switches which have buttons I8 that close the switch when depressed. Forty switches are shown mounted with 5 rows across and 8 rows down.

A card [9 is received in the card receiving slot I4. The card is shown in detail in Figure 5. It has openings formed in alignment with the buttons l8 of certain switches. As shown in Figure 3, when an opening aligns with the button l8 of the switch, it passes through. The channels l5 allow the buttons to extend through the card. This is the condition of the upper switch in Figure 3. However. when the card does not have an opening in alignment with the button Hi, the switch is closed Thus, if a card is cut in different manner, a number of combinations of closed switches may be obtained. The switch combinations may be used to control a number of mechanisms, as for example, shaft positions as explained in the prior referenced patent application.

To place the card into slot II, a cam-plate 20 is mounted to the plate l2 by links 2| and to the plate I3 by links 22. A handle 23 is received in a slot 24 formed in plate 12 as best shown in Figure 4. When pulled upwardly relativeto Figures 2 and 4, it moves the plate l3 away from the switches It so that the card may be inserted or removed. After the card is inserted the lever 23 is pivoted downwardly to move the plate l3 into position relative to the switch buttons I8, as shown in Figure 3.

Thus, it is seen that this invention provides means for storing information on a card so as to actuate a plurality of switches in a predetermined fashion.

Although this invention has been described with respect to particular embodiments thereof, it is not to be so limited as changes and modifications may be made therein which are within the full intended scope of the invention, as defined by the appended claim.

We claim:

Information-storing means comprising a base plate, a plurality of switches mounted on said base plate, a contact attached to each switch and extending outwardly therefrom, a plurality of stand-offs connected to said base plate, a second p'late slidably connected to said stand-offs, a third plate rigidly connected to said standoffs, a camming mechanism connected to said second and third plates to move said second plate relative to the base plate, a plurality of channels formed in said second plate in alignment with the buttons of said switches, a cardreceiving slot formed in said second plate, and a card formed with a plurality of openings received in said slot.
